1 Workshop on Drought identification and alert Northern Tunisia Conceptualization of a wireless network of drought Presented by: assessment Walid Fantazi Tahar Ezzedine Zoubeida Bargaoui (ENIT) Sidi Bou Said, May 2016

2 Project Context Outline Definition of WSN Application domains of WSN Integration of WSN in GIS Application 2

3 Project Context Application Project Context The main idea of this project is to implement an intelligent system to help low incomes farmers to face drought impacts. This system aims: to connect wireless sensors measuring environmental data linked to drought indicators (temperature and humidity of soil and air, pluviometry, etc...). to install a spatio-temporal database communicating with a Web mapping application for a monitoring in real time. 3

4 Project Context Application Project Context This new technique allows to study the temporal evolution of the environment parameters from which we can extract the drought phenomenon indicators. Spatio-temporal conceptual models seek to answer the users who need to manage soil water content for irrigating, fertilizing or other activities for pursuing crop yield augmentation. The study will be applied in Siliana watershed Northern Tunisia. 4

5 Project Context Application Wireless Sensors Network Definition - Group nodes sensors put in the area of interest and communicating with each other via a wireless connection. objective -Monitoring of Area and environmental parameters Characteristics - Heterogeneity of nodes -Scalability for deployment -Ability to withstand harsh environmental conditions -Ease of use 5

6 Project Context Application Application Domains of WSN Industry Ecology Agricultural/ Environmental Forest fire detection Military Health 6

7 Project Context Integration of WSN in GIS to create an automatic decision system for the natural observed phenomena Data centralization Processing model Data base Données Collection de of phénomène environmental observé data Outil decision d aide à la décision support system Consultation et Affichage des consult and données sur le web display data 7

8 Contexte du projet the adopted procedure Implement the conceptual spatio-temporal model WSN location Implementation of spatio-temporal queries, for example: -Detect Data of sensor situated in position A (x, y) obsreved during the last 5 minutes -Detect Data of sensor situated in 2 positions: B (x1, y1) and C (x2, y2) observed between two times T1 and T2 indexation of real-time data Data consulting via a web mapping application 8

17 Conclusion In this project we implemented an intelligent system using wireless sensors network to help low incomes farmers to face drought impacts. a spatio-temporal database communicating with a Web mapping application for monitoring, in real time, environmental data linked to drought indicators This tools help, for example, to answer the users who need to manage soil water content for irrigating, fertilizing or other activities for pursuing crop yield augmentation. This system will be installed in Siliana watershed Northern Tunisia 17
